Right-handed pitcher Jim Henderson has been placed on the disabled list with tendinitis in his right biceps, the Mets have announced. Left-handed pitcher Sean Gilmartin has been recalled from Triple-A Las Vegas to fill the void left in the bullpen.
Henderson got off to a phenomenal start with the Mets, striking out seven of the first nine batters he faced across three scoreless appearances. After spending the entire 2015 season in the minors due to a second shoulder surgery, the fact that Henderson has hit 96 MPH on his fastball was encouraging. Unfortunately, the 33-year-old has struggled after his early-season success, recording a 4.84 ERA and a 5.85 FIP over his next 28 appearances, with 23 strikeouts, 13 walks, and five home runs allowed in 22.1 innings pitched.
To take Henderson’s roster spot, the Mets have recalled left-handed pitcher Sean Gilmartin. Over the course of two seasons, the 26-year-old former first-round pick has a 2.45 ERA and 2.62 FIP, including five scoreless innings this year. He held a 4.48 ERA with 68 strikeouts and 19 walks over 70.1 innings in Triple-A Las Vegas.
If all else fails, perhaps Gilmartin can be used as a super-secret bench weapon; he hit .333/.429/.389 in 23 plate appearances with the Las Vegas 51s. Don’t expect him to hit quite that well at the major league level, though—these gaudy numbers come in the hitter-friendly Pacific Coast League.
